In order to answer important questions about ecosystems and
biodiversity, scientists can look to the past geological recorda
"which includes fossils, sediment and ice cores, and tree rings.
Because of recent advances in earth scientistsa (TM) ability to
analyze biological and environmental information from geological
data, the National Science Foundation and the U.S. Geological
Survey asked a National Research Council (NRC) committee to assess
the scientific opportunities provided by the geologic record and
recommend how scientists can take advantage of these opportunities
for the nationa (TM)s benefit. The committee identified three
initiatives for future research to be developed over the next
decade: (1) use the geological record as a a /natural laboratorya
to explore changes in living things under a range of past
conditions, (2) use the record to better predict the response of
biological systems to climate change, and (3) use geologic
information to evaluate the effects of human and non-human factors
on ecosystems. The committee also offered suggestions for improving
the field through better training, improved databases, and
additional funding.
